Kenny Levinsen d50bbf0bbc backend/session: Remove logind backend 
This is instead delegated to libseat.

Simon Ser 73137ace84 backend/session: fix KMS device filtering 
As explained in [1], user-space should perform a drmModeGetResources
call to figure out whether a device supports KMS.

Manuel Stoeckl a290d7a78d Make implementation function lists static const 
This requires a change to the type of `struct wlr_tablet` and
`wlr_tablet_init` signature, both of which are part of the unstable API.

Simon Ser e8d56ca415 backend/session: allow wlr_session_find_gpus to return an error 
Sometimes wlr_session_find_gpus will encounter an error. This is
different from finding zero GPUs.

On error, wlr_session_find_gpus already returns -1. However, this is
casted to size_t, so callers uncorrectly assume this is a success.

Instead, make wlr_session_find_gpus return a ssize_t and allow callers
to handle the error accordingly.

Simon Ser 754179dacd backend/session: add a timeout waiting for GPUs 
If a GPU doesn't show up in 10s, bail out and return zero GPUs.

Simon Ser 0e76f92de7 backend/session: replace session_signal with events.active 
This is more idiomatic wlroots API. The new name makes it clear that the
signal is emitted when wlr_session.active changes.

Simon Ser fbf11a41e1 backend/session: wait for DRM device if none found 
Wait for a DRM device if none is found in wlr_session_find_gpus. This
can happen if the compositor is loaded before the display kernel driver.

This supersedes the logind CanGraphical property.

To test, e.g. with i915 and sway:

    rmmod -f i915
    sway &
    modprobe i915

Closes: https://github.com/swaywm/wlroots/issues/2093

Simon Ser 76bcddf071 backend/session: introduce wlr_session.events.add_drm_card 
This is triggered when a new DRM card is added.

An easy way to test this patch is `modprobe vkms`.

Simon Ser 768fbaad54 backend/session: filter udev events by sysname 
We're only interested in card devices. The loop over wlr_session.devices
would take care of ignoring non-card events, but a future patch will
listen to udev "add" events as well.

Simon Ser 44a4792fd8 backend/session: operate on wlr_device 
Instead of operating on FDs in {open,close}_device, operate on
wlr_devices. This avoids the device lookup in wlr_session and allows
callers to have access to wlr_device fields.

For now, we use it to remove wlr_session_signal_add and replace it with
a more idiomatic wlr_session.events.change field. In the future, other
events will be added.

Simon Ser 63df2bcbe6 backend/session: don't return FD on failure in open_file 
When wlr_session_open_file fails, don't return the FD, otherwise the
caller will think the call succeeded.

Antonin Décimo 68b4a5305e backend/session: non-void function should return a value 
With assertions disabled, it should make sense to return NULL.

Simon Ser ca45f4490c Remove all wayland-server.h includes 
The documentation for wayland-server.h says:

> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.

Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.

emersion 8efeca528f backend/session: add noop session 
This is the first step towards being able to run via DRM leasing and on render
nodes.

Test with:

    export WLR_BACKENDS=drm
    export WLR_SESSION=noop
    export WLR_DRM_DEVICES=/dev/dri/renderD128

Use #if instead of #ifdef for wlroots config data 
This prevents some annoying issues when e.g. not including wlr/config.h or
making a typo in the guard name.

Add support for WLR_SESSION env variable 
Valid values are "logind"/"systemd" and "direct". If WLR_SESSION is set,
only its value is potentially tried; it will not try any other option.

Ilia Bozhinov cb42e16f64 session: load GPU devices even if they have zero crtcs/connectors/encoders 
On some systems (most notably laptops with two GPUs) there are GPUs that
don't have attached outputs. However, we still want to load those GPUs
because they could still be used by the compositor for rendering.
